Re: Can not get routes to advertise to ISP

How are you confirming that this is not working?

For instance, what is the result of "show bgp [vrf xxx] neighbor x.x.x.x advertised-routes" ?

Does your ISP require any sort of IRR registration to allow them to receive routes?  Do they rely on ARIN IRR's?

Or, your ISP is looking for your routes, and not seeing any advertised to them?

Re: Can not get routes to advertise to ISP

Yes this would be true although ISP would have to add same multihop distance I believe.

No, add on both devices is best practice by cisco, but they mentioning that if you input just in one device it will work normally.
